Short answer. DIY is cheaper when the lock was built to be rekeyed at home and you still have a working key. A locksmith is cheaper the moment the keys are gone, the lock is commercial, or a botched attempt means buying all new hardware. The person searching this wants to know which side of that line they are on.
That is the answer for the homeowner. This post is for you, the locksmith owner. Because the DIY searcher is the cheapest customer you will ever reach, and almost nobody in your trade is talking to them honestly.
Key points.
- DIY lock searches are cheap clicks. In our October 15, 2026 pull, "how to rekey a lock" cost $1.01 a click. "Lock change near me" cost $17.24.
- The lock makers now sell DIY. Kwikset sells rekeying in seconds, and Schlage is rolling out its own home rekey system.
- The page ranked first for this question has a cost comparison section with no costs in it.
- Your best weapon is a price table that includes an in-shop rekey price. That is the DIY person's middle option.
- Write the honest how-to, mark where DIY breaks, and put your number right there.
The DIY Searcher Costs a Fraction of the Emergency Call
We pulled Google Ads data through DataForSEO on October 15, 2026, for the whole United States. Look at what each click costs on the DIY side versus the hiring side.
What a Click Costs. Hire Words vs DIY Words
The five DIY phrases in brass add up to 10,800 searches a month in that pull. "How to change a door lock" and "how to unlock a car door" each showed 2,900. "How to rekey a lock" showed 2,400. "Rekey kit" showed 1,600, and "how to install a deadbolt" showed 1,000.
Now think about who those people are. A homeowner who just closed on a house. A landlord between tenants. A guy staring at his car keys on the seat. Some of them will finish the job alone. A lot of them will get halfway, drop a spring on the carpet, and need a locksmith tonight. The question is whose number they see when that happens.
Advertisers pay $15 and up to reach that same person after the panic sets in. You can reach them a step earlier for the price of a good page.
The Honest Answer Your Page Has To Give
Do not write "always call a pro." The reader knows that is a sales line, and the lock makers have already told them otherwise.
Kwikset's SmartKey page calls it the first DIY rekeying product on the market. It says a SmartKey lock rekeys in a few seconds and three steps, and it needs no experience. The catch is printed right there too. You need the current working key and the SmartKey tool, and it only works on Kwikset locks.
Schlage is going the same way. Its Advanced Rekey page says no professional skills are required, as long as you have the working key and the rekey pin. It works only on Schlage SC1 Advanced Rekey locks, and the page lists it as coming soon through trade partners. Both brands say the same thing when the key is lost. Call your builder or a locksmith.
So the honest line is simple. If the lock was built for home rekeying and the key is in your hand, DIY wins. Everything else is where your shop earns its money.
What It Actually Costs, With Real Numbers
The pages ranking for this question do not give a single price. So here is one shop that does. ACME Locksmith in Phoenix posts its rekey prices on its rekey cost page, updated October 2, 2026.
| Option | What ACME lists | What it means for the reader |
|---|---|---|
| DIY on a Kwikset SmartKey | $0 with the working key and tool | Hard to beat. Your page should say so. |
| Bring the cylinder to the shop | $20 to $35 per keyhole, no service call | The middle path for a handy person |
| Mobile service call | $95 to $125 in business hours | This is the part DIY people are trying to avoid |
| Mobile rekey per keyhole | $25 to $35 each | Added on top of the service call |
| Full three door home, mobile | $170 to $395 | The number a new homeowner is really comparing |
Prices vary by city, and these are one shop's numbers, not a national average. But look at the shape. The lock work is cheap. The trip is what costs money. The DIY searcher is not really asking "locksmith or me." They are asking "can I skip the trip."
That is your opening. Give them a way to skip the trip and still pay you.
Where DIY Breaks
We audit a lot of locksmith websites. The ones that win this searcher list the failure points plainly, step by step. These are the ones every DIY page should name.
- No working key. Both Kwikset and Schlage need the current key to rekey. Without it, the reader is calling you or buying new locks.
- Wrong brand kit. A rekey kit is made for one brand of keyway. Kwikset says SmartKey works only on Kwikset locks.
- Many doors on one key. Matching the front, back, garage and deadbolts to one key takes care and the right pins. One wrong pin and a door stops working.
- Commercial and mortise hardware. Storefront and office doors use cylinders and lock bodies that home kits are not made for.
- Car keys with chips. A car key that has to be cut and programmed is not a rekey kit job.
- Lockouts. A pry bar or a coat hanger can turn a lockout into a broken door or a scratched car.
Each of those is a real call. Put your phone number next to each one.
How To Win the DIY Searcher
Here is what we build for locksmith clients, in order.
1. Write the Real How-To
Explain how to rekey a lock the way you would teach a new apprentice. Pull the cylinder, use the key to turn the plug, push the plug out with a follower, swap the pins, put it back and test it. Use your own photos of each step.
This is not giving the store away. Google's own guide to helpful content asks whether a page shows first hand expertise, and it flags pages that leave readers feeling they need to search again. A locksmith who has rekeyed thousands of cylinders can write that page better than any home blog.
2. Add a Stop Box at Every Failure Point
Right where the reader might get stuck, add a short box. "Lost the old key? Stop here and call." "Springs went flying? Bring the cylinder in." Each box gets your phone number. That is where DIY readers turn into calls.
3. Post an In-Shop Rekey Price
The handy reader does not want to pay for a trip. Give them the ACME option. Pull the cylinders, bring them in, pay per keyhole. You get a job with no drive time, and they get a price they can say yes to.
4. Put Your Price Table Next to the DIY Cost
Show the kit route, the shop route and the mobile route side by side. Be honest that DIY wins on a SmartKey lock with a key. That honesty is what makes the reader trust your other prices. We cover this kind of page in our guide to locksmith service pages that rank, and why clear prices beat low prices in who is the cheapest locksmith.
5. Target the Cheap Words On Purpose
Build one page each for "how to rekey a lock," "how to change a door lock" and "can I rekey my locks myself," with your city in the examples. Add the FAQ with FAQPage schema. Our locksmith keyword list has more DIY phrases worth a page.
6. Track the Calls From These Pages
DIY pages make calls days later, not in the same visit. Tag the phone numbers and forms on them so you can see it. Here is how to track locksmith leads by page.
What the Top Results Get Wrong
We pulled the live Google results for "is it cheaper to use a locksmith or DIY" on October 15, 2026. An AI Overview sat on top. The first organic result was a local shop page with a section called Cost Comparison that does not list one dollar figure. Next came two Reddit threads that are eight and nine years old, a 2023 shop blog that promises to compare costs and never does, a 2021 page about rekeying versus replacing, and two Facebook posts.
Not one result answers the question with a number. Not one mentions that Kwikset and Schlage now sell rekeying to homeowners. Not one offers the in-shop option.
That is a weak page one. A locksmith with real prices, real photos and an honest "here is when to do it yourself" can own it. And the reader who learns from you is the reader who calls you when the spring hits the carpet.
If you would rather have us build it, we take one locksmith per zip code.
